Warming the tube under warm water can help to loosen the zinc. However, we hear you.
We do have the zinc in a jar now. It is available online (just ask for it in the comment section for now).
Some people prefer the tube because they take it to the beach , but we agree with you that it can be difficult to get out towards the end. PErsonally, I prefer the new tub container, but we will continue to offer both. Thank you for writing.
